Go to settings, scroll down to delete. Make sure you check “Delete Posts and Comments”
Comments should get auto-overwritten with “deleted by creator” (you can actually see the edit logo whete you wouldn’t otherwise see with a normal delete) then it gets deleted which would also show the same “deleted by creator” text, but I don’t think posts also get overwritten, they just get deleted. Images are locally stored on the instance so they should all be gone when it deletes.
You could also try a script, I never tested any.
There is probably a high likelihood of there being one instance that will refuse the request.
For the future, assume all Posts/Comments are public forever and just use Tor. Privacy doesn’t exist on a public forum, you goal should instead be anonymity, not privacy.
Assuming the lemm.ee admins delete the entire servers when it shuts down, any IP logs should be gone unless someone (admins or hosting servers) kept a copy of the logs.

If Barbra Streisand cannot delete her name from her house on the Internet, you cannot delete your comments. The Internet only forgets when you don’t want it to. If you want it to forget, it never will.
Posting a comment on the Internet is something that can never be undone. Once it’s out there, it’s out there forever. You can try and delete it, and you might make some progress, you might even be successful, but there are no guarantees, and the more you want it to be deleted the less likely you’ll be able to pull it off.
In a practical sense, just use to built-in features to delete your account and posts. It’s not perfect or guaranteed, but it’s the best you’re going to get.
